  Gage Installation Techniques

 
Environmental Protection
 
This sequence details the correct application of protective coatings for strain gage installations in a laboratory-like environment.


Coatings protect against moisture and other contaminants which might affect gage stability. Both encapsulated and open-faced gages, and their leadwire connections, must be protected.

A protective coating should be applied as soon as practical after gage installation even in an air-conditioned laboratory. Several preparatory steps generally apply to all protective coatings.
  Preparatory Steps
  Leadwire Treatment
  Coating Application
M-Coat A, C, and D
M-Coat W-1
M-Coat 3140 and 3145 RTV
M-Coat F
